Description and Introduction

Synchronous Step-Down Voltage Regulator [Not recommended for new designs] The LM2631MTCX-ADJ is a switching regulator manufactured by National Semiconductor (NS). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4V to 35V  
- **Output Voltage Range:** Adjustable (1.25V to 35V)  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 260kHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TSSOP-16  

### **Descriptions:**  
- The LM2631MTCX-ADJ is a step-down (buck) switching regulator with an adjustable output voltage.  
- It is designed for high-efficiency power conversion in applications requiring a regulated DC output.  
- The device includes an internal N-channel MOSFET switch for reduced external component count.  

### **Features:**  
- **Adjustable Output Voltage** via external resistors  
- **Internal Soft-Start** to reduce inrush current  
- **Current Mode Control** for improved transient response  
- **Thermal Shutdown** and **Overcurrent Protection**  
- **Low Power Standby Mode** for reduced quiescent current  
- **Synchronous Rectification** for higher efficiency  

This information is based on the manufacturer's datasheet.
